The original Sapphire virtually created the personal LED light industry, and millions of lights later, continues to lead the innovation charge. Unlike the countless keychain lights that are built to be cheap, today's Sapphire is a serious, precision lighting instrument that is built to ASP's demanding law-enforcement standards and made to last. The Sapphire is rechargeable, using the included adapter or any micro USB phone/electronics charging cord. A combination pressure/slide switch allows either intermittent or constant activation of a 20 lumen Nichia LED that's bright enough to light any room. Tough, polymer frame is finished with beautiful, unbreakable, aluminum side panels with polished metallic trim and blue line inset. This design is recognized around the world as a tribute to law enforcement-the police are said to be the "thin blue line" that separates order from chaos. A durable, carabiner-style spring clip that makes the light easy to attach to a bag, belt loop, key ring or zipper pull cord. The Sapphire is a must-have, take-anywhere light for home, auto, outdoors and travel. Includes convenient USB to Micro USB adapter.
